Hi,
I have a HP Proliant NL40 configured with Nexenta.
Current config:
*16GB RAM
*3 SATA disks 250 GB RAIDZ with 2 mirrors for log and cache (Kingston entrerprise ssd's of 120 GB)
*OS on 60GB mirrored drive OCZ Vertex
Please advise on this (what I could change to current config):
--------------------------------------------------------------------------------------
1.buy two laptop disks for os and install os on it (mirrored)
2.put some extra sata disks (4) in, I have 5x 2TB Seagate barracuda in my Synology NAS (RAID5)
=> I thought of using the same Barracuda 2TB x 4, then I could swap in case of issues (and don't need to go to store the same day a disk crashes)? If not these disks, which would you recommend?
3. I would only use the Nexenta for ESXi, so I don't need that much storage then (only 2 or 3TB max) UNLESS I would also put my data on it (documents), would you recommend or not? If not, then maybe smaller disks would optimize performance?
4.use the 3 SSD's of my ESX-servers (60 GB OCZ) for log (mirror) and
=> cache 1 disk? => I could order an extra one if it would be worth it
5.then I have 4 ssd's of 120 GB (Kingston), here I wonder what the best is I could do: use 2 of them as swap file location + host cache for my two ESX-es, then I still have 2 ssd's of 120 GB, one could fit in a laptop I barely use, the other ...
I guess there is no use adding 2 SSD's of 120 GB per ESX.
6.What technology/ies have you running for storage NFS or ISCSI?
7.Do you have other things installed on ZFS system, f.e. ftp, monitoring ...?
I had comment already the SSD's of 120GB are overkill, so that's why I'm looking for optimizing the use of my config, hence the question. SSD's of 60 GB (OCZ) would better fit for log/cache then the 120GB Kingston, but then again they are enterprise version ssd's.
Please advise.

2. Low Power, 5,400rpm disks are fine, because you are using SSD cache
3. we use for CIFs (Windows Shares)
4. Memory in the Server is also used for ARC cache (so more than 1 SSD is probably overkill!)
5. Yes, see my EE Articles
HOW TO: Tag and Configure a storage device as a Solid State Disk (SSD) in VMware vSphere 5.0 or 5.1 (ESXi 5.0 or ESXi 5.1)
HOW TO: Configure Host Cache Configuration for your VMware vSphere 5.0 or 5.1 ESXi (5.0 or 5.1) Host Server
6. We use both NFS and iSCSI
60GB or smaller SSDs are better for logs and cache.
7. No we do not have any other monitoring, these are SANs.
